Dog erythrocyte antigen (DEA) 1,DEA 4 and DEA 7 typing results. (A) Dog erythrocyte antigen (DEA) 1 immunochromatographic typing strip results were graded from positive (strong, moderate, and weak) to negative (no band). (B) Typing results of 2 DEA 4+ donors showing many small agglutinates by the paper card method. No DEA 4− dogs were found. (C) DEA 7 typing results of 3 donors by the gel column method. Blood samples agglutinating at the top of (4+) and/or within the gel (2+; 3+) were typed as DEA 7+, whereas when all RBCs resided at the bottom, the sample was considered DEA 7−. For all samples, a negative control column with phosphate‐buffered saline (PBS) was included.
